Description of Alternatives Endangered Fish Research Independent Review Panel(s). The review panel(s) would be comprised of qualified individuals not otherwise participating in the long-term moni- toring and research studies. Responsibilities would include reviewing resource-specific technical studies and providing technical advice. The review panel(s) would be established by the Secretary in consultation with the National Academy of Sciences, the tribes, and other AMWG entities. Further studies of the linkages among endangered fish, their habitat, and Colorado River flows would be undertaken as part of the Adaptive Management Program. Included in these studies would be an initial phase of hypotheses building and risk assessment which could lead to reopening Endangered Species Act consultation with FWS. Humpback Chub Razorback Sucker Endangered fish research flows likely would be between 8,000 and 20,000 cfs with a steady pattern and monthly release volumes during the spring through fall months similar to the Seasonally Adjusted Steady Flow Alternative. The actual flows would be developed by the AMWG through a scientific process. Research may require as many as 5 low-release years (annual release at or near 8.23 maf). Since low water release years are expected to occur only about half the time, it is uncertain how many total years it would take to complete the studies. However, it is likely that research flows could be completed within 10 years. Upon completion of the research flows and analysis of data, Reclamation would implement any necessary changes in operating criteria to comply with the Endangered Species Act. Monitoring and Protecting Cultural Resources The existence and operation of Glen Canyon Dam has had an effect on the historic properties within the Colorado River corridor of Glen and Grand Canyons. These properties include prehistoric and historic archeological sites, along with Native American traditional cultural properties and resources. Impacts are likely to occur to some of these historic properties regardless of the EIS alternative chosen for implementation. The National Historic Preservation Act, as amended in 1992, instructs Federal agencies to develop measures to avoid or minimize loss of historic properties resulting from their actions. Due to potential impacts of any dam operation, Federal agency compliance with sections 110 and 106 of the National Historic Preservation Act will be required. Glen Canyon Dam EIS Summary
